Evaluate the expression: \({\left( -13 \right)}^{2} - 4 \cdot 2 \cdot 5\)
MathBot Answer:
\[{\left( -13 \right)}^{2} - 4 \cdot 2 \cdot 5 = 129\]
\[\begin{aligned}{\left( -13 \right)}^{2} - 4 \cdot 2 \cdot 5& = \left(-13\right)^{2} - 4 \cdot 2 \cdot 5\\& = 169 - 4 \cdot 2 \cdot 5\\& = 169 - 8 \cdot 5\\& = 169 - 40\\& = 129\end{aligned}\]
